4 Claims. (Cl. 131-202) This invention relates to a cigarette holder, and more particularly to a cigarette holder having a disposable container portion for collecting nicotine, tars and other deleterious products ordinarily encountered in smoking cigarettes and the like.

The principal object 'of this invention is to provide a holder wherein the nicotine and other deleterious products may be collected in a chamber between the cigarette holding portion and the bit portion of the holder; to provide a collecting container for the holder which may be disposed of at frequent intervals and replaced with a new container; to provide the container with a screen at one end thereof to control the flow of smoke to the users mouth; to provide the other end of the disposable container with a closed end and having an inwardly extending stem portion provided With a longitudinal opening therethrough and through the closed end.

A still further object of the invention is to provide a copper or other metal wire cloth with smoke passage means through the center thereof and consisting of an integral wire screen having a relatively large imperforate annular crushed portion and a central foraminous portion to limit the porosity of the screen and to provide a device of this character, simple and economical to manufacture.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth by way 'of illustration and examples certain embodiments of this invention.

FIG. 1 is an enelarged longitudinal cross-section through the cigarette holder.

FIG. 2 is an enlarged elevational view of the holder with parts shown in disassembled relation.

FIG. 3 is an enlarged cross-section taken on a line 33, FIG. 1.

FIG. 4 is an enlarged cross-section taken on a line 44, FIG. 1.

FIG. 5 is an elevational view particularly illustrating the opening in the metal wire cloth screen filter.

FIG. 6 is an elevational fragmentary cross-section of the screen filter.

Referring more in detail to the drawings.

1 designates a holder for a cigarette (not shown) comprising a cigarette holding portion 2, a thimble or disposable container 3 and a bit portion 4. The cigarette holding portion is circular in cross-section, and the inner end is recessed or oflset, forming a shoulder 5 for receiving the reduced end 6 of a thimble or disposable cylindrical container member which has its body offset forming a shoulder 7 which engages against the end 8 of the cigarette holding member 2. The body near the opposite end of the disposable container is also reduced forming a shoulder 9 against which the end 10 of the bit portion 4 engages. The bit portion is tapered as indicated at 11 and the ends of the disposable container are telescopingly and frictionally fit into the open ends of the bit and holding portions. The bit portion has a central bore 12 as is the usual practice.

The disposable container 3 has a closed end 13 and an inwardly extending cylindrical stem 14 provided with a longitudinal bore 15 therethrough and extending through the closed end 13 of the container. The purpose of the stem is to prevent the nicotine, tars and other deleterious products from passing into, the hollow bit portion and into the smokers mouth.

The inside diameter of the end 6 of the disposable container portion is slightly greater than the inside 16 of the body portion forming a shoulder 17 facing the cigarette holding portion of the holder. A filter member 18 of circular shape is provided and adapted to engage on the shoulder 17 of the disposable container 3 as illustrated in FIG. 1.

The filter comprises a piece of copper or other suitable metal wire cloth having spaces between the wires and by use of a die the wires are pressed or compressed together over the major portion of the screen and leaving a portion in the center thereofnot crushed together, thus, leaving a screened opening 19 in the filter. The purpose of the use of the die is to crush the wire to flatten the same and to close the spaces to prevent smoke from passing therethrough and limit the amount of porosity of the filter. The cross hatching or total open transmission area of the screened opening 19 is equivalent to the area of an unobstructed opening of .027 inch in diameter.

'The filter is slightly dished as illustrated in FIGS. 1 and end of the cigarette to prevent tobacco from clogging the opening should the cigarette be pressed into contact with the filter. I

The dishing of the filter is preformed through the die crushing operation. The thimble or disposable container port-ion is made of Plexiglas or other material which is transparent, light and disposable and which may be readily displaced with a new one.

The cigarette smoke containing vaporized t-ars and other vaporized undesirable matter passes through the screen opening 19 into the container 3. The compressed rim 20 surrounding the screen, portion is integrally connected therewith and acts among other things for cooling the screen opening 19 by conduction through the wires. This allows the transfer of a significant part of the heat in the smoke to the wires of the screen opening resulting in dropping the temperature of the smoke as it enters the container 3 thus substantially aiding in the condensation of the vaporized tars and other undesirable vaporized matter in the container.

It will be obvious from the foregoing that we have provided an improved cigarette holder having a disposable thimble or container for nicotine, tars and other deleterious matter wherein a filter is provided in one end thereof made from a wire cloth material crushed to leave an opening in center thereof for filtering smoke therethrough. It will further be obvious that when the container is partially filled with nicotine, tars and other deleterious products it may be quickly removed and replaced with a new one. It is to be further understood that while one form of this invention has been illustrated, described it is not to be limited to the specific form or arrangement of parts herein described and shown except insofar as such limitations are included in the claims.

What we claim and desire to secure by Letters Patent 1. In a cigarette holder having a cigarette holding por-- tion, a bit portion and a container portion secured therebetween for collecting nicotine and the like from said cigarette, a filterin said container, said filter consisting of a mesh screen having the openings over a major portion thereof crushed together so as to be imperforate, leaving an opening in substantially the center thereof, thereby limiting the porosity of said filter.

2. The cigarette holder of claim 1 wherein the end of the container opposite the filter is closed and provided with an inwardly extending stern having an opening longitudinally therethrough for travel of smoke therethrough into said bit portion.

3. The cigarette holder of claim 1 wherein said filter is dished away from the holder portion to provide a space between the end of the cigarette and the opening in said filter.

4. The combination of claim 1 wherein said screen openings in said filter opening have a total open transmission area equivalent to the area of an unobstructed opening of approximately .027 inch in diameter or less.
